2 Why is Lab Safety Important?
Lab safety is a major aspect of every lab based science class. Lab safety rules and symbols are needed so that students do not injure themselves or their classmates.

3 Lab Safety Rules 1. Always follow the teacher’s directions and only do lab work when a teacher is present. 2. Conduct yourself in a responsible manner at all times. No Horseplay! 3. Do not touch any equipment, chemicals, or other materials until told to do so. 4. Do not eat food, drink beverages, or chew gum in the lab. Do not use lab glassware as food or beverage containers 5. Report ALL accidents to your teacher immediately, even if you think it is minor.

4 Clothing Wear: Do NOT Wear: Goggles/safety glasses Closed-toed shoes
Clothing made of natural based fiber such as cotton Tie back long hair Do NOT Wear: Sandals Jewelry Loose or Baggy clothing

5 Lab Safety Equipment Safety Shower Eye Wash Safety Goggles

6 Lab Safety Equipment Fire Extinguisher Fire Blanket Fume Hood

7 Lab Safety Symbols Found in your textbook
Glassware Heat Eye and Face Sharps Electrical Animal Chemical Fire

8 Other Chemical Hazards and Symbols
Flammable Explosive Toxic/Poison Irritant Corrosive Environmental

9 Chemical Hazard Symbols and Definitions
Flammable – Any substance that will burn if exposed to an open flame. Explosive – A substance that may explode if exposed to heat or flame.

10 Chemical Hazard Symbols and Definitions
Toxic/Poison – A substance that can lead to death if inhaled, ingested, or absorbed by the skin. Corrosive – A substance that can destroy or burn living tissue and can eat away at other materials.

11 Chemical Hazard Symbols and Definitions
Irritant - A substance that causes inflammation upon contact with skin or mucous membranes. Environmental - Substances that are harmful to the environment. They must be disposed of properly, not washed down the drain.

12 Accidents and Injuries
Report ALL accidents and injuries to your teacher immediately!!! Be aware of safety hazards associated with each chemical you use. Eye accident – Wash the eye with copious amounts of water for at least 15 min. Fire Burns – Stop, Drop, and be covered with a fire blanket or soaked with water. Do not remove clothing stuck to victim. Get medical attention immediately.

13 Waste Disposal First ask your teacher where/how to dispose of waste.
Never pour anything down the drain unless you are told to do so. A waste bottle will be supplied for substance that cannot go down the drain

14 Reasons for proper waste disposal
Hazardous chemicals down the drain can lead to pollution of ground water, lakes, rivers, etc. Plants and animals will die if they are exposed to hazardous chemical waste. Serious health problems will become present in people if hazardous waste finds its way into drinking water.
